Nice to have your artistic identification with the instrument I build. Many thanks, Emmett.

Thank you all for the comments
@Boaz: you know, I though of putting some image that relates to the instrument specifically, like the triangle were we have the tuners and actually it led me to one question I've asked myself quite often. Not wanting to begin any argument over different instruments, I've always wondered why do all tapping instruments look like the stick there? I mean, it should be really easy to come up with a different shape for that part of the instrument.. In my imagination, triangular head means stick... Just saying.

I think it looks GREAT the way it is. AND you got Emmett's approval. So "Stick" with it! (and I totally "got" it right from the get-go) (that's an "Americanism" from an American)

If you wanted to include a visual representation oc the Stick, you could make the R merge into a Stick as an underline...putting the headstock/tuners on the end, and frets / strings going back towards the R.
